The IESG has approved the following document: - 'Session Initiation Protocol (SIP) Recording Metadata' (draft-ietf-siprec-metadata-22.txt) as Proposed Standard This document is the product of the SIP Recording Working Group. The IESG contact persons are Alexey Melnikov, Ben Campbell and Alissa Cooper. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-siprec-metadata/ Technical Summary: This document describes the metadata sent between a Session Recording Client (SRC) and the Session Recording Server (SRS) in a recording of a Session Initiation Protocol (SIP) session as described in draft-ietf- siprec-protocol. Working Group Summary: This document has had a relatively long gestation period in the working group, but there has been strong consensus on the direction and text of the document for some time. There were no notable disagreements within the working group over the development of the document. On the contrary, once the protocol draft was finished, this document converged relatively rapidly to consensus. Document Quality: There are multiple interoperable implementations of drafts of this protocol. Notably, the National Emergency Number Association (NENA) has included the protocol, with the metadata described in this document in itâ??s Next Generation 9-1-1 standard, and has held an interoperability event where multiple implementations were tested. Feedback from the event has been incorporated in the draft. There are at least 8 implementations known to the document shepherd that are completed, in process, or planned. Personnel: Brian Rosen is the Document Shepherd. Alissa Cooper is the Responsible Area Director.
